The Potter Waterflow Alarm Switch Model VSR is a vane type waterflow switch for use on water mist systems. It is UL Listed and FM Approved for use on steel pipe; schedules 10 through 40, sizes 2" through 3" (50 mm through 80 mm). LPC approved sizes are 2" through 3" (50 mm through 80 mm).
The VSR may also be used as a sectional waterflow detector on large systems. The VSR contains two single pole, double throw, snap action switches and an adjustable, instantly recycling pneumatic retard. The switches are actuated when a flow of 10 GPM (38 LPM) or more occurs downstream of the device. The flow condition must exist for a period of time necessary to overcome the selected retard period.
The VSR switches and retard device are enclosed in a general purpose, die‐cast housing. The cover is held in place with two tamper resistant screws which require a special key for removal. A field installable cover tamper switch is available as an option which may be used to indicate unauthorized removal of the cover.
